Been there. Done that. I agree that each person's experience is different.

I also agree that it may be helpful to read about this subject with an eye to reaching a heightened understanding of those symptoms your wife might experience. Note that the key word is "might".

That said, it seems to me that expectations sometimes cause things to happen {or at least we might view things that happen through the lens of our expectations}. So if you expect that your wife will
"go crazy" during the long time [years not months] that she is going through menopause then you may look for evidence of this in the way she "lives and moves and has her being". And these attitudes and behaviors may be caused by other physical, mental, and/or emotional variables or mayjust the normal way that she might cope with what life dishes out to her.

Life is crazy. Therefore, to paraphrase two folk saying, let the day's crainess be sufficient for the day and dont look for trouble or trouble will look for you. In other words, don't expect your wife to be any more wacked during menopause than she is already. And if she is wacked ["crazy"}, this might be her normal way of responding to what life has dished out to her.
